Plants that cutworms attack
Comments (21)B.t. isrealensis shows little to no activity on anything but Diptera pests i.e. mosquitos and biting flies. there may have been a repellent effect, but it should not have effected any worms. B.t. kurstakii or aizawa are the strains that work on lepidoptera pests ( worms) B.t. tenebrionis is the strain that works on beetles Beet Army Worm are a very hard pest to kill. High rates of Spinosad SHOULD take care of them, but it isnt working as well as it once did in commercial applications. The nice thing about spinosad is it is a very safe chemical and in certain formulations ( Entrust) it is OMRI organic certified. It is made from the fermentation of a bacterial byproduct. The biggest problem in commercial production is that Spinosad is pretty expensive, 6 dollars an ounce x 6 oz to the acre plus application cost of ~$8.00 or more per acre. Cutworms can usually be easily controlled by a directed spray of a pyrethroid around and on the base of the plant. Keith...See MoreCutworms Cutting Down My Beans
Comments (9)Hello Jim, sorry to hear about your bean plants. If it's any consolation, mine are being devoured by something also, but I think it's slugs, but cutworms have been at it also. I reseeded the other day. This may be one of those barriers you won't have time for, but I thought I'd post it for all those other eyes that traverse these pages. Posted by gardenlad 6b KY (My Page) on Thu, Mar 22, 07 at 7:37 Quote: In order to feed, a cutworm has to entirely circle the plant stem, and make full contact. Anything that prevents that protects the plant. All I do is use wooden matchsticks. I lay a match vertically against the stem, and push it about halfway into the soil. Then, for extra security (in theory, just the one will do it) I put a second match on the oppostie side of the first one. Since I started doing this, no plant so protected has been attacked by cutworms. Unquote. The post appeared in the thread, "Collars for cutworm prevention?" in the Bean Forum. I sure miss Gardenlad's posts; wished he was still around on the Bean Forum. Hope you get your bean plants up and running despite the cutworms....See MoreCutworms
Comments (1)Hi carole6, I want to help you any way I can because I had such a battle with cutworms when I first started gardening. You can put "cutworm collars" around your plants. Tuna cans pushed into the ground about an inch, cardboard toilet paper tubes, toothpicks near the stems of your plants --all these will help. Tricogramma wasp are beneficials you can order by mail that will help. I had climbing cutworms so I went out at night (give them some time to start climbing up to feed after the sun goes down) with a flashlight and picked them by hand. It took some time but I can't tell you how satisfying it was to get 'em after they shredded so much of my plant foilage before I caught on. (Sounds like I'm still not over it!) Good luck and Happy Gardening to you! Sally...See MoreCutworms and raised beds
Comments (10)I had my first cutworm infestion just past Christmas in a 4x12, lost nearly all the mustard spinach and the bok choi was eaten down to the stalks in just three days time (approx 16 sqft). I suspect I will be using DE for the winter garden this year. My solution to removal was to take off the plastic and hoops and place 3 chickens in the bed. If anyone has any suggestions as to how fight them, please let me know....See Moregawdinfever Z6
